I had trouble getting into this book, so didn't finish reading it. Here's what it says on the back:
L.A. based private detective Regan Reilly heads to Las Vegas to help out her old school chum Danny Madley. Danny is producing a reality TV show featuring three married couples who have all suffered the proverbial "Seven Year Itch," but are now vying for a chance to renew their vows in a wedding-cake-shaped hot air balloon-and win one million dollars! But Danny has received an anonymous letter warning him to halt production, and "accidents" start happening on the set. It's up to Regan to find out what's lurking behind the scenes...After all, the show must go on!

RELEASE NOTES:

Left on a table in the waiting area.

EDIT: My dr is moving to a new office, so I brought all my books back home with me. I will re-release this later.
